Summary: The study investigated the source efficiency and wave directivity of three Kuril Islands tsunamis, concluding that the 2007 event had the most well-defined energy flux directivity, while the 1994 event had the most isotropic energy radiation. Radiation patterns of each source showed the fraction of wave energy radiated into the open ocean and the paths of wave energy propagation.

Summary: Probabilistic Tsunami Hazard Assessment (PTHA) is a method used to estimate tsunami recurrence and hazard in the South Kuril Islands. It is based on historical tsunami observations and ranks tsunami height datasets for each coastal location. By examining data from 63 coastal locations in the region, a single regional recurrence function is identified. This function includes scale parameters for the frequency of major tsunamis and characteristic tsunami heights for each location. An example application of the method is the construction of a preliminary tsunami hazard map for the South Kuril Islands, with analysis of potential errors in estimated tsunami parameters and recurrence.

Summary: A historical review of biological enhancement and fisheries for Iturup Island shows that enhancement has increased chum salmon numbers significantly, while pink salmon are primarily produced naturally. The waters near the island are considered one of the most productive marine areas in the Russian Far East due to favorable natural conditions. Efficient hatcheries and favorable conditions led to a substantial increase in chum salmon catches from less than 100 tonnes in the early 1990s to over 20,000 tonnes in the late 2010s. Understanding the factors controlling salmon production in the Kuril Islands could help scientists in other regions of the North Pacific understand the control of their own salmon populations.

Summary: This study investigates the tsunami resonance oscillation and its impacts along the south Taiwan coast based on the synthetic assessment of tsunamis induced by the 2006 Pingtung earthquake doublet. The results reveal the occurrence of edge waves along the south Taiwan west coast in most oscillation modes and the frequency-dependent energy amplification responsible for large tsunami heights and strong tsunami-induced current velocities along the south Taiwan coast during this past tsunami.

Summary: Three credible tsunamigenic scenarios were selected to assess the local tsunami hazard for Xiamen city, China. The simulation results showed that the local tsunamis hit Xiamen within 1.5 hours of earthquakes with an inundation depth ranging from 1.2 to 3.0 m. The coastal areas of southern Haicang district and eastern Siming district were identified as the most vulnerable areas.

Summary: In this study, the local tsunami hazards induced by the Quanzhou fault along the coastlines of Putian, Fujian Province in China were explored. The simulation results showed that the tsunami wave would hit the nearest coast of Putian half an hour after the earthquake. The most serious tsunami inundation depth in Putian was less than 3.0 m. Sensitivity tests were also conducted to examine the tsunami amplitude and inundation in response to different seismic source parameters, particularly the rake and strike angles of the Quanzhou fault.

Summary: This study investigates the feasibility of enhancing marine gravity field using SAR altimeter-derived gravity data. The results demonstrate that incorporating SAR gravity data significantly improves the accuracy of the marine gravity field, especially in areas close to land/island.

Summary: In this study, meta-honeycombs were designed by adding local resonance plates (LRP) to improve impact resistance. The negative mass and directional bandgap properties of the LRP were investigated to predict the impact resistance of the meta-honeycombs. Experimental and simulation results verified the effectiveness of three meta-honeycombs with different core structures in protecting against impact and blast waves. The mechanical properties of the meta-honeycombs were further optimized by coupling different resonators in the LRP.

Summary: Site characterization is crucial for understanding the damage distribution and designing measures to strengthen and create structures in metropolitan areas like Durres after an earthquake. This study investigated the local site effects in Durres using ambient noise measurements and the HVSR method. The clustering of examined sites into four categories with similar properties and the zoning map can be used as a first-level seismic microzonation for the city.

Summary: This paper compares the National Structure Inventory with a local tax assessor building inventory in modeling seismic-tsunami hazards. The study focuses on the city of Seaside, Oregon, and finds significant differences in input attributes at the parcel level, but more consistent results when aggregated at larger spatial scales. The National Structure Inventory consistently underestimates structure value and number of stories compared to the tax assessor data, and is more accurate when aggregated at increased spatial scales.

Summary: This study analyzes the impact of government relocation on residential property prices in Hangzhou, China. The findings suggest that the effects of government relocation on property prices are concentrated in certain spatial and temporal dimensions, with the strongest impact observed in the first year following relocation.

Summary: This study used a geographic information system and economic modeling to assess the economic impact of tsunamis in Japan. The aqua sector was found to be unable to recover within financial capabilities, while the recreation sector could recover but at significant fiscal and social costs. The recovery of the food processing sector may generate social benefits and have a spillover effect on other fisheries sectors.

Summary: Local governments have been important players in China's economic development, relying on their monopoly on land supply to attract investment at low prices. However, this practice has had negative environmental consequences. Despite central government's efforts to regulate environmental issues, local governments have not adequately adjusted their behavior regarding industrial land transfer. A study analyzing data from more than 280 Chinese cities between 2008 and 2018 found that the Low-Carbon City Pilots program has significantly reduced industrial land transfers by local governments.

Summary: Understanding the attitudes and beliefs of healthcare professionals regarding COVID-19 vaccines is crucial, as they are trusted sources of information. A survey-based study revealed that demographic factors, education, role at the hospital, perceptions of the pandemic, and location of work and residence significantly contribute to vaccine attitudes. Interestingly, the location of residence was found to have a significant impact on vaccine receptivity, independent of the number or severity of COVID-19 cases in the respective boroughs.
